The American University Operations And Supply Chain Management Assignment Help - Repeat the Problem


Question - Repeat the Problem 1.31 including a contact resistance of 0.1 K/W at each of the interfaces. Problem
1.31: A section of a composite wall with the dimensions shown in the schematic diagram below has
uniform temperatures of 200°C and 50°C over the left and right surfaces, respectively. If the thermal
conductivities of the wall materials are: kA = 70 W/(m K), kB = 60 W /(m K), kC = 40 W/(m K), and kD
= 20 W/(m K), determine the rate of heat transfer through this section of the wall and the temperatures
at the interfaces.
GIVEN
Composite wall
Thermal conductivities:
kA = 70 W/(mK)
kB = 60 W/(mK)
kC = 40 W /(mK)
kD = 20W/(mK)
Surface temperatures
Left side (TAs) = 200°C
Right side (TDs) = 50°C
Contact resistance at ea ...Read More
